Sony VGN-Z790Y Power Adapter
Because Sony has been known to use a single AC adapter that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. Upon choosing a replacement adapter, selecting the Sony OEM charger is the best one to choose. A universal AC adapter can be used if you are desperate. If your decision is to purchase a different brand charger, make note of both the volts and amps outputs. The Sony VGN-Z790Y power adapter provides two functions, to charge up the main battery and powering the laptop.
Signs of a barely functioning AC adapter
- The majority of Sony power chargers will get warm to the touch when plugged in for 10 minutes or more
- The unit will not operate using just the AC power adapter
- Your Sony battery refuses to charge every time

It is in your best interest to re-check the manufacturers part number before buying a power adapter replacement. Make sure to try and order replacement parts from a site you know when you buy online.
